Mario Galaxy was released for the China Nvidia Shield recently and not too long ago Twilight Princess was released as well. Based on teardowns of the APK the games are running in an emulated version of the console.
Obviously, it is possible for Dolphin to do such a thing as well but we won’t be able to do it without help. it has been rumored for some time that one or two of the main dolphin devs that were working on Android have been acquired by Nvidia.
